Minibian

Just last week, I was mentioning the existence of Minibian which is basically a Raspbian Jessie but with a minimum set of pre-installed packages.

Raspbian Jessie... Light

And a couple of days ago, the "Raspbian Jessie Light" was anounced! (I don't know if it is linked to the Raspberry Pi Zero release, but one can say that they were focused on reducing things this week!)

I haven't tried this new distribution yet but it can be downloaded on the official download page and more info about it is available on the forum.
